Fire as a Potent Mutagenic Agent Among Plants

Many of the earth's species-rich floras are fire-prone and current research is showing a key role for fire in their evolution and diversification. However the mechanisms by which fire might direct evolution at the cellular level are unknown. Mutagenesis is the foundation on which speciation is based and our literature survey shows that burning biomass may be a major source of potent mutagens in the form of heat, combustion products and recycled...
